How To Take Bacteria Samples

Sampling Air For Bacteria
Bacteria air samples are taken by impacting air onto some suitable growth media. Two of the commonly used samplers are Andersen (N6 Single Stage) and Reuter Centrifugal sampler (RCS). The Andersen sampler uses petri-dishes while the RCS uses agar strips. For environmental bacteria, a general purpose media such as Tryptic (Trypticase) Soy Agar (TSA) can be used.

Sampling Surfaces For Bacteria
Sterile cotton swabs can be used to sample for bacteria contaminating surfaces. The swabs are then sent immediately to a laboratory for culturing and identification of the bacteria to genus or species.
